Application filed May 2, 1912. Serial No. 694,614.

To all whom it may concern:

Be it known that I, JosErH '13. ST. Hnnnns, a citizen of the UnitedStates, and

a resident of Rochester, in the county of' Monroe and State of New York,have vented a new and Improved Metallic Box, of which the following is aspecification.

This invention relates to metallic b xes and is a continuation in partof applicants application, serially numbered 542,524, filed:

February 7, 1910.

The object is to provide a metallic box,

and a blank therefor, that may be shipped and stored with the blank fromwhich the box is formed in its flattened out condition and from whichthe box may be readily formed by bending up the blank, to form the sidesand ends of the box, along suitably creased lines. The side and endmembers of the box have interlocking flaps:

adapted to be readily folded to locking position to rigidly hold andsecure the sides and ends of the completely formed 'boX in' their normalpositions without the aid of solder or rivets or any fastening meansother than such as is formed by the inter-. engaging and inter-lockingsides and end;

members themselves.

The accompanying drawings illustrating a box In accordance with myinvention are as follows: 7

Figure 1 is a plan view of the blank from which the body of the box ismade. Fig. 2

is a plan view of the blank from which the cover is made. Figs. 3, 4 and5 are plan, side and end views respectively of the body of the boxcompletely formed. Fig. 6 is a side view and Fig. 7 an end view of thecover completely formed. Fig. 8 is an enlarged transverse sectional Viewof the box taken along the line m-y of Fig. 4, but with the coverthereon, while Fig. 9 is a longitudinal sectional view of a partof thebox taken along the line c -g of Fig. 5.

Referring to the drawings,similar parts are designated by similarletters of refer-. ence throughout the several ffigures of the drawings.

The body of a'box in accordance with my invention is formed from ablank, such as seen in plan view in Fig. 1, having-a bottom member Bbounded on each of its four sides with a crease, as indicated at o, and

.on the outer sides of the longer creasesare seen side members A, eachhaving a finer crease extending longitudinally thereof in.-

dicated at the dotted lines 1 and 4 and also having at each end thereofa similar and transversely extending crease, indicated at the dottedlines 6 and 7. Beyond the finer creases l and 4 are seen portions aadapted, when bent down as indicated in Figs. 13, 4, 5, .8 and 9, toform cover engaging and holding flaps or extensions. At the endsof eachof these side members A there are seen j triangularly shaped flaps Fadapted to be bent up at right angles with the sides A. These lockingflaps F have locking ears f thereon. Along the line of the finer creasesl and 4 in the sides A are seen slits s adapted to receive the lockingflaps Z later to be described. The ends of the box E have fine creasestherein, as indicated at the dotted lines 5 and -S, beyond which areseen the flaps 0 while along the line of the creases 5 and 8 are formedslits u adapted to receive the looking ears f. At the lends voit each ofthe end members E, and beyond the fine creases indicated .by dottedlines 2 and 3, are seen locking flaps D each carrying a locking ear cladapted to engage through the slits s in the sidemembers A.

In forming a box from such a blank the members A and E are bent up .toform the sides and ends of the box with the flaps, carried by one ofsuch pair of opposite mem- ,bers, engaging within the inside of the boxand with the flaps,,carried by .the.other pair of such oppositelydisposed members, engaging outside of the boX,iIl the drawings I haveshown the flaps D as engaging outside of the sides A and the fiapsF asengaging inside of the ends E. Before bending up the sides andends, asjust above described, it is preferable to bend the locking earsfontwardly and away from the observer, with reference to Fig. 1 alongthe dotted lines indicated where they unite with the flaps F while theears (Z on the flaps D,are similarly bent toward the observer. As thebox is formed from the blank the ears f are inserted so as to extendoutwardly through the slits a while the ears cl are insertedso as toextend inwardly through the slits s,- after outside of the box in such away as to be spaced from the sides A to comprise engaging and holdinmeans for the slidable cover.

The cover is formed from a blank, such as seen in plan view in Fig. 2and comprises the main central portion C, bounded by suitable creaselines o and having side flaps 0 adapted to be folded inwardly along thefine crease lines, indicated at the dotted lines 9 and 10, and withinbut spaced from the flaps o, as clearly indicated in Fig. 8, so as toreceive the cover holding flaps a between the parts 0 and 0 The cover isprovided with end flaps P adapted to be folded down along the heavycreases v to form the ends of the cover and each of these end flaps l"?in turn is provided with an extension member 72 adapted to be formedaround a suitable rod or core 0*, as indicated in Fig. 6, and one of theend flaps as indicated in this figure may be folded downwardly to finalposition while the other one, as seen at the left in Fig. 6, may remainin its straightened out position until after being inserted over the boxafter which, when desired, it may be bent down in the same way as theone seen at the right hand end of the cover in Fig. 6. To facilitate thelocating of the core or rod r and the forming of the roll around thesame the flaps 1 may have fine creases formed therein as indicated atthe dotted lines 11 and 12.

From the foregoing description of my box and the blank from which thesame is formed it is believed that the coiiperation of the several partsthereof is sufficiently clear to call for no further explanation herein.

What I claim is:

1. A metallic blank for a box comprising a centrally disposed bottommember having side members extending outwardly theref om; one of theadjacent ends of adj acent side members carrying an end fiap adapted,when said adjacent side members are bent to position to form sides ofthe box, to be bent to lie against and in a plane parallel with theother side member and having its upper edge extended in a linecomprising the upper edge of the box and substantially coincident withthe upper edge of the side of the box formed by the other side memberand said other side member having a longitudinally extending side flapadapted to be bent down over said first named flap whereby said firstnamed flap operates, by engagement in the line of the fold between thesecond named side member and the longitudinally extending side flapthereon when folded down over the first named flap, to hold the firstnamed side member against outward movement independently of anyfrictional engagement of such first named flap against and between thesecond named side member and the longitudinally extending side flapfolded down therefrom, said second named side member having a slittherein approximately at the fold between the same and thelongitudinally extending side flap thereon and the end flap on saidfirst named side member carrying an ear or lug adapted to engage throughsaid slit and be folded down against the other side member.
